Export "Supplier Reconciliation Statement" to Excel with Java (Merge & Grouped Reports)

JQuick-ExcelMerge & Grouped Reports

Merge & Grouped ReportsScene 0032

Groups monthly reconciliation by supplier, computing Variance Amount = Our Payable - Supplier Reconciliation per row, with a variance subtotal row after each supplier and a grand total row at the end; the supplier-name column is vertically merged into one block. Java only groups and pre-processes the rows; all statistics and layout are declared in XML.

Supplier Reconciliation Statement — Merge & Grouped Reports

About this demo

This demo exports the "Supplier Reconciliation Statement" workbook: 1 data sheet(s); MAPPING over 6 columns (供应商, 对账月份, 我方应付, 供方对账, 差异金额, 差异说明), 11 formula(s), 7 style rule(s). On the Java side it only builds the data and calls exportSupplierReconciliation() once — everything else is driven by the config.

It belongs to the "Merge & Grouped Reports" group: MERGE group blocks with SUBTOTAL/TOTAL rows: each group column merges into one vertical block, every group closes with a subtotal and the report ends with a grand total.

What you can copy from this page

  • The complete Java test class (96 lines, runnable as-is)
  • The complete XML config (44 lines: mapping, formulas, styles, charts and every other rule)
  • The exported xlsx file (real output, comparable with the preview above)

Minimal invocation (4 lines)

The core is these four lines: hand the rows to the parser, the parser to the factory, get a typed Service and call it. Copy them straight into your project.

// rows 由业务代码构造（List<JQuickRow>），os 为输出流，见下方完整源码
JQuickParseHandler parser = new JQuickExcelExportXmlParseFactory("mintFresh", rows, os);
JQuickFactory factory = new JQuickXmlFactory(parser, XML);
Merge0032SupplierReconciliationService service = factory.createApi(Merge0032SupplierReconciliationService.class);

XML config · 0032_merge_supplier-reconciliation.xml

Formats (FORMAT), formulas (FORMULAS) and styles (STYLE) are all declared in this XML, fully decoupled from the Java code. The full config is below — copy it as-is.
